Phi Phi Island Diving | Phi Phi Island Articles by hotelATM

Phi Phi Island diving conditions are fairly consistent with dives during different seasons having their own unique advantages.Phi Phi has a small tide so the conditions are changing all the time. Westerlies in low season effect visibility.

Dive conditions in Koh Phi Phi are variable according to weather and conditions but you can dive Phi Phi all year round. The best conditions are during February to May when the waters are at their warmest and clearest. The average visibility around Koh Phi Phi is 15 – 20 meters, some days the visibility extends to 30 meters.

Water temperature is normally around 30 degrees centigrade year round, only rarely dropping to 27 degrees at it’s coldest . During the high season between October and May the wind comes from the direction of Krabi, weather is sunny and wind conditions are good allowing access to all dive sites including those further afield like Hin Daeng and Muang and Koh Haa.

Low season diving conditions

During the Green Season between June and October the weather can be changeable with occasional monsoonal storms and high waves. During this time, trips to Hin Daeng, Hin Muang, King Cruiser Wreck and Koh Haa are weather permitting and not as regular as in high season. If the weather conditions are inclement, Phi Phi dive schools opt for larger dive boats instead of long tail boats even for local Phi Phi dive sites, as safety is always the first priority.

Late May to October brings south westerly monsoon winds and surface swells to the islands, lowering visibility by about 25%, but it's pretty rare that diving trips are canceled due to bad weather.
